AUTOMATIC CUT-OFF.

SPECIFICATION forming part of Letters Patent No. 718,012, dated January6, 1903. Application filed October 18,1902- Serial No. 127,809. (Nomodel.)

To all whom it may concern:

Be it known that I, BENJAMIN-F. D. MILLER, a citizen of the UnitedStates, residing at Wooster, in the county of Wayneand State of Ohio,have invented new and useful Improvements in Automatic Cut-Offs, ofwhich the following is a specification.

My invention relates to automatic cut-ofis for drain -spouts connectingwith eavestroughs, and has for its object to construct a device whichwill permit the dirty water from the first rain that falls after anextended dry period to waste and not contaminate the cistern and thenautomatically operate to permit the remainder of the water to run intothe cistern. i

The simple and novel construction employed by me in carrying out myinvention is fully described and claimed in this specification andillustrated in the accompanying drawings, forming a part thereof, inwhich Figure l is aside elevation of my device. Fig. 2 is a longitudinalsection of the same. Fig. 3 is an edge elevation of the gear-casing withthe threaded shaft bearing the weight.

shown in section.

Like numerals of reference designate like parts in the different viewsof the drawings.

The numeral 1 designates an inverted Y having a stem 2 and arms 3 and 4,constructed of piping. The stem 2 is constructed to be coupled to adrain-pipe (not shown) at a point near the ground, the arm 3 isconnected to a pipe 5, (shown only in fragment,) which connects with acistern, and the arm 4 is connected to a spout 6, set to discharge wateronto the ground. Mounted in the stem 2 at the junction of the arms 3 and4is a valve 7, carried by a horizontal shaft 8, bearing a crank-arm 9,situated outside of the pipe and constructed to assume its elevatedposition whenthe valve is set to close the arm 3. A water-wheel 10 ismounted horizontally in the spout 6 and is adapted to be operated by thewater flowing through the spout. The wheel 10 is keyed on a verticalworm-shaft 11, which meshes with a large gear 12, located in asemicircular casing 13, connected to the spout 6. The gear 12 is keyedon a shaft 14,

which is journaled in the casing 13 and extends beyond the same.

The outer end of the shaft 14 is threaded at 15 for a portion of itslength to adapt it to engage a threaded boss 16, formed on the upper endof a slotted weight 17, which is connected to the crankarm 9 on thevalve-shaft S by a flexible member 18.

When a rain is expected, the arm 9 is raised up, so that the valve 7will direct the water to the spout 6 and prevent its entering "thecistern-pipe 5, and the weight 17 hung on the inner part of the threadedportion 15 of the shaft 14. As soon as the water starts running down thespout 6 it will turn the water-wheel 10 and drive the shaft 11, whichweight 17 out to the end thereof, when it will drop off, therebylowering the crank-arm 9 to rotate the valve and cut off the water fromthe spout 6 and direct it into the cistern-pipe 5. The length of timethe water is allowed to runto waste can be regulated by varying thepoint at which the weight 17 is set on the threaded portion 15 of theshaft 14.

I do not wish to be limited as to details of construction, as these maybe modified in many particulars without departing from the spirit of myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In an automatic cut-off fordrain-spouts, the combination with two intersecting pipes, of a valvelocated at the junction of said pipes, a water-wheel mounted in one ofsaid pipes, a shaft having a threaded end, means connecting said shaftand said wheel, a weight constructed to engage the threaded end of saidshaft and to be displaced therefrom by the revolution of said shaft, andmeans connecting said weight and said valve, substantially as described.

2. In an automatic cut-off for drain-pipes, the combination of awaste-spout and a cistern-pipe forming a junction, a valve mounted atsaid junction, a shaft having a threaded portion, means operated by theflow of water through said waste-pipe to drive said shaft, a weightconstructed to be engaged by the threaded portion of said shaft and tobe displaced therefrom by the rotation thereof, and

means connecting said valve and said weight to operate said valve whensaid Weight falls off of the said shaft, substantially as described.

3. In an automatic cut-off for drain-pipes, the combination with awaste-spout and a cistern-pipe forming a junction, a shaft bearing acrank-arm and a valve which is located at said junction, a shaft havinga threaded end, a weight constructed to engage the threads on said shaftand to be disengaged therefrom by the rotation of said shaft, meansconnecting said weight and said crank-arm, a waterwheel mounted in saidwaste -spout, and means connecting said shaft and said Waterwheelwhereby said shaft is driven, substantially as described.

4. In a device of the class described, a shaft having a threaded end,means for driving said shaft, a Weight constructed to engage thethreaded end of said shaft and to be disengaged therefrom by therotation of said shaft, and a valve constructed to be operated by saidweight on being disengaged from said shaft, substantially as described.

5. In a device of the class described, the combination of a waste-spoutand a cisternpipe forming a junction, a worm-shaft bearing a water-wheelmounted in said spout, a shaft having a threaded end and bearing a gearlocated to mesh with said worm-shaft, a weight constructed to engage thethreads on said shaft and to be displaced therefrom by the rotation ofsaid shaft, a shaft bearing a crank-arm and a valve which is located atsaid junction, and a flexible member connecting said crank-arm and saidweight, substantially as described.

6. In an automatic cut-off for drain-pipes, the combination with awaste-pipe and a cistern-pipe forming a junction, a crank-shaft bearinga valve located at said junction, a shaft having a threaded end, aslotted weight bearing a threaded boss engaging said shaft, a flexiblemember connecting said weight and said crank, a Water-wheel mounted insaid waste-pipe, and means connecting said waterwheel and said threadedshaft, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witmesses.
